Thanks for the response, I actually figured it out.

If I run GE-Proton9-27, Frame Gen works fine. If I use anything newer than GE-Proton9-27, I get the DLSS option, but only AMD FSR3 Frame Generation - It seems like a regression with recent Proton builds, as it also happens under Steam Proton 10.

I might try running a newer version of Proton when I get time and see if the launch option you've quoted resolves the issue, right now I'm just glad to have Frame Gen working again.

My biggest issue gaming under Wayland is the fact that certain games can't capture the mouse when run full screen with multiple monitors. I've got a number of games that exhibit the issue, but the easiest way to experience it is to try and run CS2 as wayland native (so not under xwayland - As the performance overheads running xwayland are notable running CS2) - Within 10 mins you'll be looking at the ground with the mouse pointer on your secondary monitor.

Furthermore, running gamescope doesn't fix the problem - And yes, I'm running the correct commands under gamescope.

I mean - This is basic functionality that should be an integral part of any modern OS. Under X11 running the same dual matched monitors everything works perfectly with great FPS.

I have no beef in this argument, and I'm certainly not biased in relation to AMD/Nvidia. However, my 980Ti, my 2070S and now my 4070S have all run really well under Linux. I run KDE Neon and a quick 'sudo apt install nvidia-driver-570' installs the latest beta's in under 5 mins, if I want to roll back the driver a quick 'sudo apt install nvidia-driver-565' has me back on the latest feature branch. Yeah, Wayland adoption under Nvidia was slow, and Nvidia's earlier choices weren't what anyone could call 'ideal' - But momentum is building, and as a result I've been using Wayland for about eight months now without issue. Before that, X11 was largely faultless running Nvidia hardware/drivers.

People say Nvidia struggle in relation to VKD3D performance. I'm not too sure what they're doing, but VKD3D runs fine here.

It's the one advantage we have over Mac users: We can run AMD, Intel and Nvidia. We also have ongoing OGL support, native Vulkan support, better game support under Steam, a larger user base under Steam, and the amazing Proton implementation.

Whether it be AMD or Nvidia, I personally think it's Linux for the win. EDIT: I in no way see value for money in the new 5080/5090 cards and I eagerly await what AMD has to offer (although I won't be switching from my 4070S for quite some time yet).
